chore(dev): run scheduler worker as a ddev daemon + document it

Add a web_extra_daemons entry so ddev auto-runs
messenger:consume scheduler_default (time-limited to 1h, supervisor
restarts it) — the unpaid-booking expiry now runs every minute in dev
without manual steps. Document both messenger workers in CLAUDE.md. In
production this consume must run under supervisor/systemd.
